ENDICOTT, N.Y. (AP) — A ceremony will be held this weekend at the high school alma mater of an upstate New York sailor who was among the victims of the U.S. Navy's worst submarine disaster.

The USS Thresher sank 220 miles off Cape Cod on April 10, 1963 while on a routine deep-diving test. Several New Yorkers were among the 129 civilian technicians and sailors on board, including 26-year-old Electrician's Mate 2nd Class Gregory Joseph Fusco of Endicott, near Binghamton.

Fusco joined the Navy after graduating from Union-Endicott High School in 1954. After he died aboard the Thresher, a memorial in the shape of a submarine conning tower was erected at the school's football field.

That's where a local group of submarine veterans will gather on Saturday for their annual tribute to the victims of the Thresher sinking.
